Severity: normal → trivial
Summary: Animation PNG frame rate is slightly fast → Animated PNG frame rate is slightly fast
This file actually used to run slightly too *slow*. In Aurora, a current cycle of this image takes 1666.39 ms, but on Nightly it's always almost exactly 1500ms. The file itself is designed to take 1500 ms. So I think this isn't a bug!
